What are structs in Go and how do I use them?

Structs in Go are composite data types that group together variables (fields) under a single name. You can define a struct to represent a complex data structure.

Can you show me an example of defining a struct?

Sure! Here's a simple example:

type Person struct {
    Name string
    Age  int
}

This defines a Person struct with two fields: Name and Age.

How do I create an instance of this struct?

You can create an instance like this:

p := Person{Name: "Alice", Age: 30}

This creates a Person instance with the name "Alice" and age 30.

Can I have a slice of structs?

Yes, you can! For example:

people := []Person{{Name: "Alice", Age: 30}, {Name: "Bob", Age: 25}}

This creates a slice of Person structs.
